| 摘 要： | 研究了盆栽条件下添加苦参腐解物对酚酸物质(香草醛和肉桂酸)胁迫下茄子生长及根际土壤微生物种群数量和土壤酶活性的影响。与对照相比,苦参腐解物处理促进了酚酸作用下茄子的株高和茎粗生长,增加了茄子土壤微生物的种群数量,尤其增加了细菌和放线菌数量。随着外源香草醛和肉桂酸浓度的增加,细菌和放线菌数量先增大后减小,而真菌数量先降低后增加;同时,茄子根际土壤过氧化氢酶、多酚氧化酶、脲酶的活性均高于对照,呈先增大后降低的变化趋势。

| Abstract: | A pot experiment was conducted to study the effects of Sophora flavescens decayed products on the growth of eggplant (Solanum melongena) and the microbial populations and enzyme activities in its rhizosphere soil under the stress of vanillin and cinnamic acid.Compared with the control,the addition of S.flavescens decayed products promoted the plant height and stem diameter of S.melongena,and increased the amounts of microbial populations,especially of bacteria and actinomycetes,in rhizosphere soil.With the ... |
